NOTE SHEET FOR AUTOMATIC MUSICAL INSTRUMENTS.

Application filed April 21, 1920.

To all who??? may concern:

Be it known that HEINRICH liooiusorr, deceased. late a citizen of the Republic of Czechoslovakia, and formerly residing at Poughkeepsie, in the county of Dutchess and State of New York, United States of American invented certain new and useful Improvements in Note Sheets for Automatic Musical Instruments, of which the following is a specification.

This invention relates to note sheets for automatic musical instruments having two or more devices for producing different 1nu-- sical effects.

The primary object of this invention is the provision of a note sheet having perforations in a single line which may control a plurality of devices operable singly or collectively to produce different musical effects.

A particular object of this invention is to provide a note sheet having perforations which will. cause to operate two stop-mechanisms of an automatic organ, and put either one or both on or off. at will, the per-- forations being in a single line in the note sheet. A mechanism with which this sheet will operate to produce the result stated, is described in the applications (Cases A. and B) of Heinrich Bockiscli and executed of even date herewith and filed in the United States Patent Office on April 21, 1920, Se rial Numbers 375,575 andv 375,576 Patent No. 1,440,763 dated January 2, 1923, respectively,

Referring to the drawing, the figure represents a plan view of a note sheet, embodying my invention, and showing the perforations for controlling the two devices for causing different musical effects such as two stops of an automatic organ. The sheet is represented as passing in a direction from the upper to the lower roll of the winding mechanism, as indicated by the arrow. The perforations for controlling the stop mechanism are shown in a single line at the right of the sheet, although it is to be understood that the particular placing of the perforations at one side of the other has nothing to do with this invention as long as the duct in the tracker with which they are to register is correspondingly placed. In the form of sheet illustrated in the draw ings, the note perforations would be placed at the left of the perforations illustrated,

and in that part of the sheet which is shown clear. The perforations of music have been omitted from the drawings since they, themselves, form no part of the present. invention.

In the drawings, 10 designates the track er having a tracker duct 11, therein. 12 designates the sheet which is shown as be ing broken because the space between the perforations is indeterminate except in the particular piece of music in which the perforations are made.

As the sheetpasses over the tracker 10 the duct 11 is opened by a hole 13 in the sheet 12. This perforation only opens the duct an instant. This impulse of air admitted to the duct 11, affects a mechanism which is functionally responsive to such an impulse and is on the same pneumatic line with an other mechanism which is not functionally responsive to such an impulse, but which is functionally responsive to an impulse of different characteristic as one of long duration. The mechanism is so constructed that changes in the musical effect do not oc cur during the time when the perforations are not registered with the duct. The change brought about by the short impulse of the opening 18 is maintained until the perforation 14: opens the duct 11. The mechanisms are so constructed that successive impulses of the same characteristics operate the stops in opposite ways. For instance the perforation 13 causes the short impulse mechanism to come on while the succeeding perforation 14 will cause it to be taken off. The mechanism is now in the same condition as before the perforation l3 opened the duct 11.

lVhen the perforation 15'" opens the duct 11, the mechanism which is more quickly responsive operates. Before, however, it can cause any change in the musical effect, the duct 11 is closed and the perforation 15 opens it. The latter operates to take off the mechanism put on by the perforation 15*, also since it is a longer perforation than the perforation 15*, the impulse is longer and the mechanism which is sensitive to long impulses operates to perform its function. Thus, we have the mechanism which is responsive to a short perforation off and that responsive to a long perforation on. These mechanisms remain in this condition until the perforation 16 reaches the tracker tion 16' takes it off again. However. as the perforation a long one the other mechanism has time to become functionally operatire and bring the second mechanism to the off condition.

It has been shown above how it was possible by this sheet to operate either met-hie nism on or ott' from the single line of per torations. i will now descrihe the perform tions for causing hoth mecl anisnis to come on at substantially the same time and also to go oil at substantially the same time.

hen the pertoration 1T uncovers t. duct 11. the first ll'lQiltlOIlitl mechanism crates to perform its unction. Since 'th perforation does not immmliatel close. th other mechanism operates to pertorz it function in the musical composition. mechanisms are 110w (ii ltlill lll fi'.

As the perl'oration 1H uncovers the duct 11, the reversing portions ot the respective mechanisms operate in a similar ntanncr to take hoth mechanisms "oti'f" A very useful application ot this invention is to the sheet used with an automatic pipe organ which ma; have many s ops in this case one line of pertorations may he used to put on and off each two stops. In this way great sawing is made in the width of the sheet.

lVhile this invention is described in connection with an auto 'iatic organ having two steps, I desire to have it understood that it is of broader application and 111a he used for expression devices on automatic musical otll ' instruments generally.

It is also to he understood that while a single line 01 perforations is shown in the drawing, it is intended to have one line of perforations tor each two stops ot the instrument.

It is mulerstood that modifications and changes in the proportions and form of the perforations dcscrihed may he made witlr out departing from the spirit of the invention and within the scope ot the appended claims.

Having described my invention what I claim is:

1. A note sheet having a line of perforations to control two mechanisms for the production of differentmusical eli'eots, said line of perforations comprising perforations of one area to control the putting in opera tion ot one of the mechanlsms and periora! ions ot the same area tor putting out o l operation the same mechanisms and pertorations of oiiicrent area to control the putti 1;; in and puttin out oi operation ot both i the liltCl'ittlilSIHFi.
